To @Z 1071,0777, it muy concern:

Be it known that I, KARL O. MUEHLBERG, a resident of Homestead, in the`county of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Hose- Connectors; and I do hereby declare thefollowing to be a full, clear, and exact description thereof. A

My invention relates to hose-connectors; and the object is to provide adevice of this character which can be applied to the hose without theuse of a tool of` any kind and which will form a secure and water-tightconnection with the hose.

All hose-couplings as now constructed comprise two members, one forattachment to each section of the hose, and wh-ich must be securedthereto by wire, bands, or other means which require special tools toapply and which generally cannot be applied tightly except by anexperienced person. My hose-connector is designed to overcome thisdefect in prior devices and to provide a connector which can be appliedto the hose without the use of a tool of any kind and by an unskilledperson and which forms a water-tight connectionwith the hose.

In the accompanying' drawings, Figure 1 is a longitudinal sectionthrough the simplest form of my hose-connector. Fig. 2 is a similar viewShowing a modification thereof; and Figs. 3 and 4 are sectional viewsshowing the invention applied to a nozzle and spigot, respectively.

In all forms of my hose-connector I provide a member 1, which isexternally threaded and provided either at one or both ends, dependingupon its use, with a projecting nipple 2, which in turn is provided ator near its outer end with anexternal annular rib or bead 3,

o this rib or bead forming, in effect, a head on the end of said nippleand preferably being provided witha sloping outer face 4, so that it canbe readily slipped into the hose, and with a sharp or abrupt innershoulder 5. In use this nipple is slipped inside of the hose 6, as shownin the drawings. Cooperating with this internal member 2 is an externalsleeve 8, having a threaded connection with the member 1, as shown, soas to be capable of moving longitudinally thereof. In the simplest formof the connector, as shown in Fig. 1, the sleeve 8 has a plain internalface and is adapted to pass externally of the hose 6, and the endthereof will clamp said hose against the shoulder 5 on the rib 3. Inthis manner the hose 6 is givena sharp bend, as shown in Fig. 1, and isclamped tightly between the rib 3 and sleeve 8. Y

In the modification shown in Fig. 2 the member 1 is also threadedexternally, and screwed thereon is an internally-threaded sleeve 9,provided with a projecting collar portion 10,which is also externallythreaded. This collar is adapted to project out over the nipple 2 and isso arranged as to leave an annular space between itself and said nipple,into which space the end of the hose will project. A supplemental sleeve11 has a threaded connection with the collar l() and is provided with aninwardly-projecting lip 12. The sleeve or collar 10 clamps the hoseagainst the inner face of the rib 3, and in addition thereto theinwardly-projecting lip 12 on the sleeve 11 clamps the hose against theouter face of the rib 3, so that the hose is clamped at two points vanda very secure connection formed.

Either of my forms of connectors may be used for the attachment of ahoseto a nozzle, as shown in Fig. 3, or to a spigot, as shown in Fig. 4. Inthis case'the member 1, with its nipple 2 and bead 3, is formed as apart of the nozzle or spigot, respectively, and the sleeve 8 is threadedonto the body thereof, as shown.

rI he clam ping-sleeve 8 of Fig. 1 and the corresponding sleeve 9 ofFig. 2 move outwardly on the body-that is,-to\vard the annularprojection 3. Back of this annular projection the body is reduced to adepth greater than the thickness of the hose. The clampingsleeve has astraight interior and as it moves outwardly will not catch the end ofthe hose and pushit oif the nipple, the space provided being sufiicientto give ample room for the end of the hose.

It will be observed that with all forms of my hose-connector no wiringor bands are needed for attaching the same to the hose, but that theattachment can be made merely by IOO the hands of the operator withoutthe use of any tool. The sleeves or other rotary members in all casesare provided with knurled or similar roughened outer faces, so that theycan be easily turned by hand. As a consequence, the connector can beapplied at any time and at any place and when applied will form a verysecure and water-tight joint with the hose. 1t is adapted for use withhose for conveying water, steam, compressed air, or for any otherhigh-pressure mechanism.

1. Ahose-connector comprisingabodyhaving a threaded exterior and aprojecting portion provided with an external annular en largementdesigned to be inserted inside the hose, said body being reduced back oithe an-4W nular enlargement to a greater depth than the lthickness ot'the hose and said annular enlargement being of less diameter than thebody, and a clamping-sleeve having a straight threaded interior toengage the threaded exterior ot' the body and arranged to move outwardlyover the hose and clamp the same against the annular enlargement.

2. A hose-connector comprising a member provided with a projectingnipple having an external annular enlargement,acollarorslceve on saidmember and located externally of said nipple to leave an annular spacetherebetween, and a sleeve having a threaded connection with said collarand arranged to pass over the hose and clamp the same against theannular enlargement of said nipple.

3. A hose-connector comprising a member provided with a projectingnipple having an annular enlargement thereon, an annular eollar orsleeve on said member and located externally of said nipple to leave anannular space therebetween, and a sleeve having a threaded connectionwith said collar and provided with an inwardly-projecting annular lipand arranged to pass over the hose and clamp the same against theannular enlargement of said nipple.

4. A hose-connector comprising a member provided with a projectingnipple having an annular enlargement thereon, a sleeve having a threadedconnection with said member and an annular space therebetween, and aclamp-l a threaded connection with said member and located externally ofsaid nipple to leave an annular space therebetween, and a clampingsleevehaving a threaded connection with said first-named sleeve and providedwith an inwardly-projecting rib orlip and arranged to pass over the hoseand clamp thc same against the annular enlargement of said nipple.

6. A hose-connector comprising an externally-threaded member provided oneach end with a projecting nipple having an annular enlargement thereon,and having at each end an annular collar located externally of saidnipples to leave annular spaces therebetween, and two clamping-sleevesinter-nally threaded and engaging said collars and provided withinwardly-projecting ribs or lips and arranged to pass over the hose andclamp the same against the annular enlargements of said nip- A ples. y

7. A hose-connector comprising an externally-threaded member provided oneach end with a projecting nipple having an annular enlargement thereon,a pair of collars internally threaded and engaging said member and inturn being externally threaded and arranged to project over said nipplesto leave annular spaces therebetween and to clamp the hose against theannular enlargements on said nipples, and clamping-sleeves internallythreaded and engaging the external threads of said collars and providedwith inwardlyprojecting beads or ribs arranged to pass over the hose andclamp the same against the annular enlargements of said nipples.

In testimony whereof I, the said KARL O. MUEHLBERG, have hereunto set myhand.
